Integer division by zero results in floating-point exception !?

The hardware exceptions are considered "part of" the D mechanisms too,
for instance dereferencing a null pointer will give you a similar error.


BTW; If I run your program (with the debugger) on Mac OS X, I get:

Program received signal EXC_ARITHMETIC, Arithmetic exception.
0x00002e21 in D main (args={length = 1, ptr = 0x300550}) at div0.d:13
13          writefln("a/b = ", a/b);

Interestingly, this only happens on X86. The PPC happily outputs:
a/b = 0

So I guess it is ultimately up to how the architecture handles it...
But for the Intel architecture you probably want to check for it ?
